Hi,
At the moment, the plugin doesn’t support a shortcode to display the donation field directly.
If you’d like to change the “Donate” text to something else, such as “Pay,” you can easily do this using a translation plugin, for example https://projectdmc.org/plugins/loco-translate/. Additionally, we’ve added a filter that allows you to change the button text. Here’s an example of how to implement it:
add_filter('wpz_change_donation_button_text', function($text) { return 'Pay'; // Replace 'Pay' with your desired text });
